Summary
A rare lesser sac hernia strangulated a portion of the intestine through the lesser omentum. This transomental hernia, identified via abdominal computed tomography, has not been previously documented.
Area of Science:
- Gastroenterology
- Surgical Anatomy
Background:
- Internal hernias, including lesser sac hernias, are uncommon abdominal conditions.
- Transomental hernias, specifically through the lesser omentum, represent a rare subset.
Observation:
- A female patient presented with symptoms suggestive of bowel obstruction.
- Abdominal computed tomography revealed a distended intestinal loop within the lesser sac, entrapped by a defect in the posterior lesser omentum.
Findings:
- The patient was diagnosed with a strangulated transomental hernia, a rare anatomical variant.
- The hernia involved a defect in the posterior layer of the lesser omentum, leading to intestinal incarceration.
Implications:
- This case highlights the importance of considering rare internal hernias in the differential diagnosis of bowel obstruction.
- Accurate radiological diagnosis using computed tomography is crucial for identifying such anomalies.
- The unique presentation necessitates awareness among surgeons and radiologists for appropriate management.
